What does it mean to have over voltage protection?
What is Over Voltage Protection? Over voltage protection is a power supply feature which shuts down the supply, or clamps the output, when the voltage exceeds a preset level. Most power supplies use an over-voltage protection circuit to prevent damage to the electronic components. The impact of an over-voltage condition varies from one circuit …
How does over voltage protection work on a crowbar?
There are various protection circuit designs, each with its merits, mode of operation, sensitivity, ability, and reliability. The protection can either clamp off the excess voltage, or completely shut down the power supply. A crowbar over-voltage protection circuit
Do you need over voltage protection for switch mode power supplies?
For both linear regulated power supplies and switch mode power supplies, some form of over-voltage protection is always advisable. As with many electronic techniques there are several ways of implementing a particular capability. This is true for over-voltage protection.
What happens when over voltage is applied to a power supply?
Prevent the excess voltage from being applied to the components. The protection circuit should not interfere with the normal function of the system or circuit. The protection circuit should not load the power supply and cause related voltage drops.

How are appliances protected from voltage surges?
Your appliances have many layers of protection against voltage surges. First, there are the fuses and/or circuit breakers in your house–they will “blow” and interrupt a circuit that becomes overloaded. Second, your larger appliances will often have an internal fuse.
